Description

La présente invention concerne un dispositif de réglage de la position d'un renvoi de sangle notam­ment de ceinture de sécurité pour véhicule automobile.The present invention relates to a device for adjusting the position of a strap return, in particular a seat belt for a motor vehicle.

Sur la plupart des véhicules, ce renvoi de sangle est disposé sur un doigt d'ancrage fixé sur la carrosserie du véhicule, à une hauteur convenant à une majorité d'utilisateurs dits de taille normale.On most vehicles, this strap return is placed on an anchoring finger fixed to the vehicle body, at a height suitable for a majority of so-called normal-sized users.

Toutefois, cette hauteur ne convient pas à certains utilisateurs, en particulier aux personnes de petite taille.However, this height is not suitable for some users, especially short people.

Pour résoudre ce problème, on connait dans l'état de la technique un certain nombre de disposi­tifs de réglage de la hauteur de ce renvoi de sangle.To solve this problem, a number of devices for adjusting the height of this strap return are known in the prior art.

Ainsi, par exemple, on connait d'après le document FR.2 484 343, un dispositif de réglage en hauteur d'un point d'ancrage d'une ceinture de sécu­rité dans lequel un coulisseau se déplace le long d'une tige support filetée dans la plage de réglage de l'ancrage, ladite tige étant montée à rotation entre les parois d'un boitier fixé à un élément de la car­rosserie du véhicule. La face frontale de ce coulis­seau porte une ferrure d'ancrage de la ceinture et sa face dorsale porte un organe d'immobilisation en ro­tation du coulisseau qui le guide le long de la paroi de fond du boitier.Thus, for example, we know from document FR.2 484 343, a device for adjusting the height of an anchor point of a seat belt in which a slide moves along a support rod threaded in the anchoring adjustment range, said rod being rotatably mounted between the walls of a housing fixed to an element of the vehicle body. The front face of this slide carries a belt anchoring fitting and its dorsal face carries a member for immobilizing the slide in rotation which guides it along the bottom wall of the housing.

On connait également d'après le document FR. 2 488 201, un dispositif pour régler la hauteur d'une ferrure de renvoi d'une ceinture de sécurité de véhi­cule, comportant un organe de réglage portant la fer­rure avec un verrou s'enclenchant dans des crans d'ar­rêt d'un guidage rectiligne, le verrou pouvant être dégagé par un mécanisme de manoeuvre.We also know from document FR. 2 488 201, a device for adjusting the height of a return fitting of a vehicle seat belt, comprising an adjustment member carrying the fitting with a latch engaging in stops of a rectilinear guide , the lock being able to be released by an operating mechanism.

On connait également d'après le document FR. 2 482 539, un dispositif pour le réglage du point d'ancrage d'une ceinture de sécurité, disposé au-des­sus de l'épaule d'un occupant d'un véhicule, dans lequel le point d'ancrage est porté par un curseur de glissière monté déplaçable dans une glissière et immobilisable en position par un cliquet coopérant avec une série d'orifices réalisés dans la glissière.We also know from document FR. 2,482,539, a device for adjusting the stitch anchor for a seat belt, disposed above the shoulder of an occupant of a vehicle, in which the anchor point is carried by a slide slider mounted movable in a slide and immobilizable in position by a pawl cooperating with a series of orifices made in the slide.

Le document FR.2 513 887 décrit quant à lui un dispositif pour le réglage de la position en hau­teur de la ferrure supérieure du baudrier d'une cein­ture de sécurité. Ce dispositif comprend une glissière solidaire de la carrosserie du véhicule, munie d'une fente de guidage et d'évidements, dans lesquels pénè­tre au moins un organe de blocage monté sur un cou­lisseau qui porte la ferrure et peut être verrouillé et déverrouillé au moyen d'un organe d'actionnement manuel.Document FR.2 513 887 describes a device for adjusting the height position of the upper fitting of the harness of a seat belt. This device comprises a slide secured to the vehicle body, provided with a guide slot and recesses, into which penetrates at least one locking member mounted on a slide which carries the fitting and can be locked and unlocked by means of 'a manual actuator.

Le document FR. 2 543 838 décrit un disposi­tif d'ancrage pour point haut de ceinture de sécurité, comprenant un rail ayant plusieurs trous qui sont en deux parties, et un ergot de blocage qui peut être commandé par un bouton de manoeuvre. Le réglage de la position du point d'ancrage est obtenu par extraction de l'ergot du trou, déplacement du coulisseau et ré­introduction de l'ergot dans un autre trou.The document FR. 2,543,838 describes an anchoring device for a high point of a seat belt, comprising a rail having several holes which are in two parts, and a locking lug which can be controlled by an operating button. The adjustment of the position of the anchor point is obtained by extracting the lug from the hole, moving the slide and reintroducing the lug into another hole.

Enfin, le document FR. 2 536 288 décrit un dispositif pour le réglage en hauteur d'une ceinture de sécurité pour véhicule automobile, constitué par une glissière de guidage comportant des deux côtés, des ouvertures de verrouillage disposées les unes au-­dessus des autres, et un chariot qui peut être déplacé dans la glissière, ce chariot portant une pièce de fixation ou de renvoi de la ceinture et comportant des éléments d'arrêt qui peuvent être déplacés transver­salement par rapport à la direction du mouvement du chariot, au moyen d'une touche en s'opposant à l'ac­tion d'un ressort, pour passer d'une position de ver­rouillage à une position de déverrouillage.Finally, the document FR. 2,536,288 describes a device for adjusting the height of a seat belt for a motor vehicle, consisting of a guide rail having on both sides, locking openings arranged one above the other, and a carriage which can be moved in the slide, this carriage carrying a part for fixing or returning the belt and comprising stop elements which can be moved transversely relative to the direction of movement of the carriage, by means of a key opposing the action of a spring, to pass from a locked position to an unlocked position.

Cependant, tous ces dispositifs présentent un certain nombre d'inconvénients, notamment au niveau des possibilités de réglage, de leur structure relati­vement complexe et donc de leurs coûts de fabrication et de montage relativement élevés.However, all of these devices have a certain number of drawbacks, notably in terms of adjustment possibilities, their relatively complex structure and therefore their relatively high manufacturing and mounting costs.

Par ailleurs, dans la plupart des disposi­tifs connus, les organes de verrouillage sont sollici­tés vers leur position de verrouillage par des moyens élastiques qui exercent sur ceux-ci, une force de maintien relativement importante. Ceci oblige l'utili­sateur qui désire déplacer le renvoi de sangle, à exercer sur les organes de déplacement de ces moyens de verrouillage, une force relativement importante pour déplacer les moyens de verrouillage vers leur position escamotée et permettre ainsi le déplacement du renvoi de sangle.Furthermore, in most known devices, the locking members are biased towards their locking position by elastic means which exert on them, a relatively large holding force. This forces the user who wishes to move the strap return, to exert on the displacement members of these locking means, a relatively large force to move the locking means to their retracted position and thus allow the movement of the strap return.

Le but de l'invention est donc de résoudre les problèmes évoqués ci-dessus en proposant un dispo­sitif de réglage simple, rapide et précis, de la posi­tion du renvoi de sangle, pour adapter celle-ci à la morphologie de l'utilisateur.The object of the invention is therefore to solve the problems mentioned above by proposing a device for simple, rapid and precise adjustment of the position of the strap return, in order to adapt it to the morphology of the user.

A cet effet, l'invention a pour objet un dispositif de réglage sur la position d'un renvoi de sangle notamment de ceinture de sécurité pour véhicu­le automobile, entre deux positions extrêmes, du type comportant un rail de guidage solidaire du montant du véhicule et sur lequel se déplace le renvoi de sangle, caractérisé en ce que ledit renvoi comporte une pre­mière portion plane à partir de laquelle s'étendent deux ailes, disposées de part et d'autre du rail de guidage, et entre lesquelles est prévue une plaque de blocage s'étendant derrière le rail, inclinée vers le bas en direction de la face arrière du rail, et adaptée pour coopérer avec des moyens de verrouillage prévus sur la face arrière du rail pour bloquer le renvoi en position, des moyens élastiques étant prévus pour solliciter la plaque de blocage en position de verrouillage et la première portion plane du renvoi en appui contre la face avant du rail, le renvoi compor­tant une seconde portion décalée angulairement par rapport à la première et actionnable par un utilisa­teur pour dégager la plaque de blocage des moyens de verrouillage et donc déplacer le renvoi de sangle.To this end, the subject of the invention is a device for adjusting the position of a strap return, in particular of a seat belt for a motor vehicle, between two extreme positions, of the type comprising a guide rail secured to the amount of the vehicle and on which the strap gear moves, characterized in that said gear comprises a first flat portion from which extend two wings, arranged on either side of the guide rail, and between which is provided a plate blocking extending behind the rail, inclined downward towards the rear face of the rail, and adapted to cooperate with locking means provided on the rear face of the rail to block the return in position, elastic means being provided for bias the blocking plate in the locked position and the first flat portion of the return bearing against the front face of the rail, the return comprising a second portion angularly offset from the first and operable by a user to release the blocking plate from locking means and therefore move the strap return.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • - la Fig.1 représente une vue en coupe d'un dispositif selon l'invention ; et
  • - la Fig.2 représente une vue de face d'un dispositif selon l'invention.
The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which:
  • - Fig.1 shows a sectional view of a device according to the invention; and
  • - Fig.2 shows a front view of a device according to the invention.

Ainsi qu'on peut le voir sur ces figures, un dispositif de réglage selon l'invention comporte un rail de guidage 1 solidaire du montant 2 du véhicule et sur lequel se déplace un renvoi de sangle 3, par exemple de ceinture de sécurité de véhicule automobi­le. Ce rail peut être muni de moyens d'habillage 4 de type connu en soi permettant d'améliorer la présenta­tion de l'ensemble.As can be seen in these figures, an adjustment device according to the invention comprises a guide rail 1 secured to the upright 2 of the vehicle and on which a strap reference 3, for example a vehicle seat belt, moves. automobile. This rail can be provided with covering means 4 of a type known per se making it possible to improve the presentation of the assembly.

La fixation du rail sur le montant est assu­rée par exemple dans la partie supérieure de celui-ci par une portion repliée 5 du rail, s'engageant dans un évidement 6 ménagé dans le montant du véhicule et dans sa partie inférieure par un ensemble vis-écrou 7.The rail is fixed to the upright, for example in the upper part thereof by a folded portion 5 of the rail, engaging in a recess 6 formed in the vehicle upright and in its lower part by a screw assembly. nut 7.

Le renvoi de sangle 3 comporte une première portion plane 8 à partir de laquelle s'étendent, comme on peut le voir plus clairement sur la Fig.2, deux ailes 9 et 10 disposées de part et d'autre du rail de guidage 1, et entre lesquelles est prévue une plaque de blocage 11 s'étandant derrière le rail 1 et incli­née vers le bas en direction de la face arrière de celui-ci.The strap return 3 has a first flat portion 8 from which extend, as can be seen more clearly in FIG. 2, two wings 9 and 10 arranged on either side of the guide rail 1, and between which a plate is provided blocking 11 extending behind the rail 1 and inclined downwards in the direction of the rear face thereof.

Comme on peut le voir plus particulièrement sur la Fig.1, cette plaque de blocage 11 est adaptée pour coopérer avec des moyens de verrouillage 12 pré­vus sur la face arrière du rail pour bloquer le renvoi 3 en position.As can be seen more particularly in FIG. 1, this blocking plate 11 is adapted to cooperate with locking means 12 provided on the rear face of the rail to block the return 3 in position.

Des moyens élastiques 13 sont également pré­vus pour solliciter d'une part la plaque de blocage 11 en position de verrouillage et d'autre part la premiè­re portion plane 8 du renvoi en appui contre la face avant du rail 1.Elastic means 13 are also provided for urging on the one hand the blocking plate 11 in the locked position and on the other hand the first planar portion 8 of the return bearing against the front face of the rail 1.

Le renvoi 3 comporte également une seconde portion 14 décalée angulairement par rapport à la pre­mière portion 8 de celui-ci et cette seconde portion est actionnable dans une direction illustrée par la flèche F sur cette Fig.1, par un utilisateur, pour dé­gager la plaque de blocage 11 dans la direction illus­trée par la flèche S, des moyens de verrouillage 12 et permettre ainsi le déplacement du renvoi de sangle vers une autre position de verrouillage.The reference 3 also includes a second portion 14 angularly offset with respect to the first portion 8 thereof and this second portion can be actuated in a direction illustrated by the arrow F in this Fig. 1, by a user, to release the plate blocking 11 in the direction illustrated by arrow S, locking means 12 and thus allow movement of the strap return to another locking position.

Les moyens de verrouillage 12 prévus sur la face arrière du rail 1 comprennent par exemple deux ailes ou nervures 15 et 16 s'étendant à peu près pa­rallèlement sur la face arrière du rail et dans les­quelles sont ménagées des encoches par exemple 17 (Fig.1) et 18,19 (Fig.2) adaptées pour coopérer avec une partie correspondante de la plaque de blocage 11 afin de verrouiller le renvoi de sangle en position. Il est à noter que les nervures 15 et 16 peuvent com­porter plusieurs encoches en regard l'une de l'autre, permettant d'obtenir autant de positions de blocage du renvoi.The locking means 12 provided on the rear face of the rail 1 comprise for example two wings or ribs 15 and 16 extending approximately parallel to the rear face of the rail and in which notches are formed, for example 17 (Fig.1 ) and 18.19 (Fig. 2) adapted to cooperate with a corresponding part of the locking plate 11 in order to lock the strap return in position. It should be noted that the ribs 15 and 16 may have several notches facing one another, making it possible to obtain as many positions for blocking the return.

Comme on peut le voir plus particulièrement sur la Fig.2, dans laquelle on a représenté les enco­ches 18 et 19 ménagées respectivement dans les nervu­res 15 et 16, le fond des encoches de chaque nervure peut être incliné en direction de l'autre nervure de manière à coopérer avec une portion arrondie 20 de la plaque de blocage, ce qui permet d'obtenir un débat­tement α de part et d'autre d'une position intermé­diaire du renvoi représentée sur cette Fig.2, afin d'améliorer le positionnement de la sangle.As can be seen more particularly in FIG. 2, in which the notches 18 and 19 formed respectively in the ribs 15 and 16 are shown, the bottom of the notches of each rib can be inclined in the direction of the other rib of so as to cooperate with a rounded portion 20 of the blocking plate, which makes it possible to obtain a clearance α on either side of an intermediate position of the reference shown in this FIG. 2, in order to improve the positioning of the strap.

Le rail de guidage 1 peut également compor­ter dans sa partie inférieure, une surface de butée 21 (Fig.1) s'étendant sur toute la distance séparant le rail du montant du véhicule pour déterminer une posi­tion de sécurité du renvoi dans le cas où par exemple, les moyens élastiques 13 se briseraient et n'assure­raient plus une sollicitation du renvoi de sangle et plus particulièrement de la plaque de blocage de ce­lui-ci, dans les moyens de verrouillage du rail.The guide rail 1 can also include, in its lower part, a stop surface 21 (FIG. 1) extending over the entire distance separating the rail from the vehicle upright to determine a safety position of the return in the event that by example, the elastic means 13 would break and no longer provide a bias on the strap return and more particularly of the blocking plate thereof, in the rail locking means.

Selon un mode de réalisation particulière­ment avantageux, ces moyens élastiques 13 comprennent une lame coudée dont l'une des extrémités est soli­daire de la plaque de blocage 11 et l'autre est en appui contre la face arrière du rail pour solliciter le renvoi en position de verrouillage.According to a particularly advantageous embodiment, these elastic means 13 comprise a bent blade, one of the ends of which is integral with the blocking plate 11 and the other of which is in abutment against the rear face of the rail in order to request the return to the position of locking.

La plaque de blocage 11 est avantageusement constituée de deux parties symétriques 11a et 11b (Fig.2) fixées l'une sur l'autre, au niveau de leurs rebords en regard, et venues d'une seule pièce avec les ailes 9 et 10 respectivement.The blocking plate 11 is advantageously made up of two symmetrical parts 11a and 11b (Fig. 2) fixed one on the other, at their facing edges, and coming in one piece with the wings 9 and 10 respectively.

Le dispositif selon l'invention permet donc d'obtenir de manière très simple différentes positions de réglage, permettant à l'utilisateur d'adapter la hauteur du renvoi à sa morphologie.The device according to the invention therefore allows to obtain in a very simple manner different adjustment positions, allowing the user to adapt the height of the reference to its morphology.

Par ailleurs, la seconde portion 14 du renvoi, décalée angulairement par rapport à la premiè­re, permet à l'utilisateur d'agir facilement sur le renvoi de sangle pour le déplacer.Furthermore, the second portion 14 of the return, angularly offset from the first, allows the user to easily act on the strap return to move it.

Enfin, il va de soi que le dispositif selon l'invention peut ne présenter que deux positions de réglage à savoir une position haute et une position basse.Finally, it goes without saying that the device according to the invention may have only two adjustment positions, namely a high position and a low position.
